ARM: imx6: reset PLL2's PFD2 on i.MX6D ...

The check for is_imx6q was introduced initially in

	f1f6d76370b3 ("ARM: i.MX6: correct work flow of PFDs from uboot-sources")

to differentiate between i.MX6DL+i.MX6SL and i.MX6Q. The i.MX6D must be
handled like the latter, so drop the check. i.MX6DL+i.MX6SL can be
ignored here since since

	a66596282413 ("imx6: lowlevel_init: Fix workaround for new i.MX6s chips")

the PFD handling is only done for i.MX6DQ.

Update the comment to be not only logically correct but also helpful.

ARM: i.MX6: Enable parent propagation for clk_gate2 ...

Enable parent rate propagation for clk_gate2 to allow the
clock consumers to adjust their rates.
One effect of this is that the i.MX6 NAND controller now can adjust
its rate. It already called a clk_set_rate(rate, 96000000), but this
had no effect, so the clock stayed at reset default 24MHz resulting
in a rather slow timing. This became a problem when commit
"1daa3bc mtd: nand_mxs: Setup timing" introduced EDO timing mode for
faster NAND chips. EDO mode can only work properly for cycle times
< 30ns (at least that's specified in the ONFI spec). 1daa3bc resulted
in sporadic NAND read errors on some boards.

ARM: vector_table: Fix creation of second level page table ...

The second level page tables can only start at a 1MiB section boundary,
so instead of calling arm_create_pte() with the high vector address
(which is 0xffff0000, not 1MiB aligned) we have to call it with
0xfff00000 to correctly create a second level page table.
The old values broke SoCs which have peripherals in the upper 1MiB
area, like for example the Atmel AT91RM9200. On these Socs we correctly
created the vector page, but the pages around it did not have a 1:1
mapping anymore which led to unreachable peripherals.
